As the Smithsonian’s National Air & Space Museum undergoes renovations for its 40th anniversary in 2016, one of its signature artifacts is being moved for the first time ever.

The Smithsonian announced today that the Apollo Lunar Module, which has been housed in the east end since it opened in 1976, has been relocated to the Boeing Milestones of Flight Hall, “the museum’s central and largest space.” The Module, the Smithsonian says, “has been placed in position to create a dramatic centerpiece for the exhibition,” and will “act as a striking welcome to visitors as they enter the museum and represent the ‘milestone’ of America’s first moon landing, in July 1969.”

To accommodate the move, the Smithsonian is planning to move another module—the Apollo 11 Command Module Columbia, to the museum’s Udvar-Hazy Center to undergo conservation (and it’ll eventually be displayed in a future gallery scheduled to open in 2020). This is significant because, for the first and only time, museum space nerds visitors will be able see both of the Apollo artifacts together in the same space.

The Apollo 11 Command Module Columbia will only be around for another two weeks though, so say your goodbyes soon.
